Causes of Bare Spots in the Lawn. Bare spots in your lawn can be the result of heavy foot traffic (causing soil compaction), drought, disease, chemical burn and weed or insect infestation. Before beginning repairs, you need to determine the source of your problem.
Gray Leaf Spot. Gray leaf spot, caused by Pyricularia grisea, causes bleached spots with dark margins on grass blades. St. Augustinegrass, fescues, ryegrasses and kikuyograss are impacted by gray leaf spot, which prefers warm temperatures, high humidity, and over-watered and over-fertilized lawns.
